Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the computer. A supervisor password and a user password can be set for the
Setup and for booting the computer, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup options. If
only the supervisor password is set, pressing <Enter> at the password prompt of Setup gives
the user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the supervisor
password or the user password to access Setup. Setup options are then available for viewing
and changing depending on whether the supervisor or user password was entered.
• Setting a user password restricts who can boot the computer. The password prompt is
displayed before the computer is booted. If only the supervisor password is set, the computer
boots without asking for a password. If both passwords are set, you can enter either password
to boot the computer.
Speaker
A 47 Ω inductive speaker is mounted on the desktop boards. The speaker provides audible error
code (beep code) information during the Power-On Self-Test (POST).
Battery
A battery on the desktop board keeps the values in CMOS RAM and the clock current when the
computer is turned off. See Chapter 2 for instructions on how to replace the battery.
